Hertz Motorcycle Audio FAQ
Which Hertz saddlebag lid kit fits my Harley?
Hertz makes the HD14H for 2014-2023 Touring saddlebag lids and the HD24H for 2024-present Touring base and CVO ST models. Both are cut-in kits for your factory lids. Hertz includes a cut-out template, 6x9 speaker mounts, speaker grilles, mounting hardware and a plug-and-play speaker harness. Speakers are not included; Hertz designed the HD14H around its 690 NEO 6x9.
What is the difference between Hertz SV and SX speakers?
SX models are coaxials with a built-in tweeter, so they drop into factory locations and play full range. SV models are SPL midrange drivers. Hertz rates the SV 200 NEO 8-inch at 200 watts continuous, 4 ohms, 100 Hz to 8 kHz, so pair it with a horn such as the ST 25K and use a crossover. Hertz states the SV 200 NEO terminals and mounting holes fit Harley-Davidson bikes.
Which Hertz plug-and-play kits fit 2014-2023 Harleys?
Hertz offers three here for 2014-2023 Touring bikes: a plug-and-play fairing kit, the HSP2 4-speaker kit for bikes with a factory Tour-Pak, and the HSP3 4-speaker kit that adds 6x9 saddlebag lid speakers. The HSP3 runs on the Hertz SP 4.900 4-channel amplifier. For 2024-present bikes, start with the HD24H lid kit and our 2024-present plug-and-play kits.

Hertz Speakers for Harley: SPL Show Coaxials, Midrange and Compression Drivers
Hertz SPL Show is the line baggers run, and it splits three ways:
- Coaxials: the SX 165 NEO 6.5", the SX 690 NEO 6x9, the SX 690 H 3-way 6x9 and the SX 200 NEO 8".
- Midrange (no tweeter): the SV 165, SV 200 and SV 250.1 10".
- Compression drivers: the ST 25A and ST 25K NEO 1" and the ST 35A and ST 35K NEO 1.4".
An SV midrange needs an ST driver or another tweeter on top. Hertz speakers aren't year-specific; the lid kits and fairing kits are.
2024-Present Hertz A2B Kits, Amps and DSP
On 2024-Present bikes, Hertz builds kits for the factory A2B system: the HSP1-24 A2B 2-speaker fairing kit, the HSP2-24 A2B 4-speaker Tour-Pak kit, the HSP3-24 A2B base kit with saddlebag lids, and the HSP3-24 A2B S3 for bikes with Stage 3 audio. The HD24H 6x9 cut-in kit covers Touring Base and CVO ST bags.
Building past a kit? The SP4.900 is a Hertz motorcycle Class D amplifier, and the S8 DSP handles the tuning. For 2014-2023 bikes, compare the HD14H lid kits and Hertz plug-and-play kits in this collection.
